Mutual redundancies and triple contingencies
1. Mutual Redundancies and Triple Contingencies
among Perspectives on Horizons of Meaning

2. Information, Redundancy,
and the Measurement of Meaning
1. Information as uncertainty (Shannon-Weaver);
expected information; bits measurement
2. “A difference which makes a difference” (Bateson);
“A distinction which makes a difference” (MacKay)
→ potentially, reduction of uncertainty; “negentropy”
→ “meaningful information” for a system of reference
(e.g., an observer)
→ redundancy + information = maximal information
→ redundancy as the complement of information
3. Replace “historically excluded” with “historically not yet
realized”
(“adjacent others” -- Kauffman, redundancy -- Weaver);
Shift of focus to the instances that could have happened.
Brooks & Wiley (1986, at p. 43): The development of the maximum information
content and the historically realized information over time.
4. Shannon-Weaver model
Shannon (1948, p. 3): “Frequently the messages have meaning; that is they
refer to or are correlated to some system with certain physical or conceptual
entities. These semantic aspects of communication are irrelevant to the
engineering problem.”
Warren Weaver argued that Shannon’s “bizarre” distinction between
information and meaning “has so penetratingly cleared the air that one is
now, for the first time, ready for a real theory of meaning” (Shannon &
Weaver, 1949, p. 27).
5. Cultural domain; Husserl’s “cogitatum”
Correlated in “language”; codingCorrelations: sharing of meaning
Weaver (1949, p.26): “Similarly, one can imagine another box in the diagram
which inserted between the information source and the transmitter, should
be labeled “semantic noise”. (…) And the problem of semantic decoding must
take this semantic noise into account.”

6. Luhmann
(Husserl, Parsons, Maturana, etc.)
• Symbolically generalized codes of
communication (Parsons, 1963; 1968):
– For example: money, power, truth, love, etc.;
• Functional differentiation of the codes as the
latent dimensions (“eigenvectors”) in the
communication matrix of senders and receivers
(von Foerster); (→ social system)
• Second-order dynamics because of three layers;
the loops can reinforce each other into
auto-catalysis (Ulanowicz; Padgett & Powell).
7. Layer 1
Networks of communications among communicating agents:
Historical proliferation of the uncertainty (entropy)
Layer 2
Interactions among communications provide meaning to the
communications at the supra-individual (i.e., systems) level
Layer 3
Codes of communication structure the interactions,
at the (next-order) “global” level
Bottom-up:
Historical construction
Top-down:
Evolutionary control
Variation and
selection
8. 1. Selections at
specific moments of
time networks
3. Some stabilizations are
selected for globalization
2. Some selections are
selected for stabilization
over time
→ Triple Helix of selection mechanisms
9. Two selection mechanisms operating upon each other generate a historical
variation (T12 ≥ 0). Three selection mechanisms operating upon one another can
generate a positive (T123 ≥ 0) or “negative” (missing) variation (T123 < 0).
Correlations are added to the relations.
10. Additive and subtractive color mixing
→ three different perspectives;
→ sharing of meaning; → generation of synergy

12. Configurational Information:
T123 = H1 + H2 + H3
– H12 – H13 – H23 + H123
→ TUIG is potentially negativeR123 < 0 : reduction of uncertainty; synergy;
R123 > 0 : historical development; exploration
Mutual Information:
T12 = H1 + H2 – H12
T12 ≥ 0; always positive
𝑹 𝟏𝟐 = 𝐻1 + 𝐻2 − (𝐻12+2𝑇12)
= 𝐻1 + 𝐻2 − ([𝐻1+ 𝐻2 − 𝑇12] + 2𝑇12) = −𝑻 𝟏𝟐
R123 = T123

P and Q can be considered as vectors rotating in the three-dimensional space of
supply, demand, and control; as component functions of innovation.

14. Semantic map among 56 title words connected at cosine ≥ 0.1
among 149 titles of documents in Social Science Information
2005-2009.
15. 1. The mutual information among the three factors in the
system of title words is T123 = +50.6 millibits.
No synergy among the three main factors in the
historical organization of the titles in a journal.
2. When the analysis is repeated for the 187 documents that
cite one of these 149 documents, T123 = –106.2 millibits;
Evolutionarily self-organization of the citing documents
into three disciplinary groupings:
(i) organizational sociology; (ii) ethnology; and
(iii) migration studies.
16. Indicator of synergy
in innovation systems
• The Triple Helix provides us with a model for
measuring the knowledge base of an innovation
system in terms of synergies
• Three sources of variance:
– geographical diversity (endowment);
– technological capacity (infrastructure);
– industrial structure
• Firms as units of analysis

Knowledge-Based Economy, Journal of the American Society for Information Science
and Technology 64(9) (2013) 1890-1902.
Statistics Sweden:
N = 1,187,421; November

48.5% of the regional
synergy is provided by the
three metropolitan areas
of Stockholm,
Gothenburg, and
Malmö/Lund.

organization.

19. Conclusions
• Relations in the network space versus correlations in the vector space;
dyadic relations versus triple contingencies (→ “triadic closure”).
• Historical relations versus Evolutionary functions
– Historical footprints; variation; observable retention
– Evolutionary differentiation; exploration of new dimensions; R > 0
– possible synergy among selection mechanisms → R < 0
• The selection mechanisms are not given, but socially constructed as
symbolic codes of the communication (res cogitans). They can be
operationalized as evolving eigenvectors of the consecutive matrices.
• The advantages of this approach are operationalization and
measurement!
